Is electromagnetic a wave?

Electromagnetic waves are transverse waves. That means the electric and magnetic fields change (oscillate) in a plane that is perpendicular to the direction of propagation of the wave. Also note that electric and magnetic fields in an EM wave are also perpendicular to each other.

How is an electromagnetic wave formed?

Electromagnetic waves are formed when an electric field (which is shown in blue arrows) couples with a magnetic field (which is shown in red arrows). Magnetic and electric fields of an electromagnetic wave are perpendicular to each other and to the direction of the wave.
